1. A gas detection system comprising:
a first sensor unit that outputs a voltage corresponding to a concentration of a specific gas;
a chamber capable of storing a sample gas; and
a control unit capable of controlling flow rates of the sample gas and a purge gas that are supplied to the first sensor unit, wherein
when supplying the sample gas to the first sensor unit, the control unit performs control so that a flow rate of the sample gas, after a lapse of a first time from a start of supply of the sample gas to the sensor unit, is smaller than a flow rate of the sample gas at the start of supply, the first time is set based on the amount of sample gas that can be stored in the chamber.
